President Yoon undergoes questioning over imposition of martial law on Dec. 3

We start today at the Corruption Investigation Office for High-ranking Officials at the Gwacheon Government Complex where President Yoon Suk Yeol is facing questions on charges of insurrection following his arrest early this morning.

For details Arirang's Choi Min-jung is standing by live on site.

Min-jung let's begin with details of the actual arrest.

Right, Sunny. President Yoon was arrested this morning at 10:33 AM,.. at his presidential residence in Hannam-dong, marking a historic moment in South Korea's political landscape.

The arrest comes 43 days after he declared martial law on December third.

He was seen leaving the residence in a convoy of security vehicles, and arrived at the CIO headquarters in Gwacheon behind me,.. where he is being held for questioning.

The interrogation began at 11 AM in a video recording room,.. focusing on the allegations of insurrection that are tied to the imposition of martial law on December third.

From 11 to 1:30 PM, deputy chief of the CIO, Lee Jae-seung, conducted the investigation,. with Yoon's legal team present.

President Yoon refused to testify during the questioning and exercised his right to remain silent.

The interrogation resumed in the afternoon at 2:40 PM, conducted by Senior Prosecutor Lee Dae-hwan.

The anti-corruption agency also mentioned that while President Yoon is currently being questioned in a video recording room, no video is being recorded due to his refusal to get taped.

The arrest comes after South Korea's anti-corruption agency executed the warrant to temporarily detain Yoon early this morning for questioning.

The operation commenced at around 5 AM,. and approximately 1-thousand personnel, including members of the anti-corruption agency and police,. were deployed to the presidential residence.

Authorities appeared better prepared than the first failed attempt.

At around 7:30 AM,.. a few dozen investigators passed through defense lines,.. by using ladders to go over the buses that were parked as barricades.

The team managed to secure entry without any major incidents, though initial resistance was reported.

Now following his arrest the president shared a pre-recorded public address.

What was the gist of his message?

Before heading here, to the CIO headquarters, Yoon released a video message saying that he decided to appear for questioning to prevent "bloodshed" between government agencies.

He, however, stressed that the investigation remains illegal.

Take a listen.

"As the president who must protect the Constitution and legal system of the Republic of Korea, responding to such illegal and invalid procedures is not an acknowledgment of them, but rather a desire to prevent any unsavory bloodshed."

Yoon's legal team argues that the CIO does not have investigative authority over the president, but also illegally sought the arrest warrant from the Seoul Western District Court, where it does not have jurisdiction.

President Yoon's side argues that the declaration of a state of emergency was a legitimate exercise of executive power.

As this unprecedented event unfolds, all eyes remain on President Yoon's next steps and how the investigation will progress.

This is all I have for now, but I'll be back with more updates on our next newscast.
